Description

Foundation composition of peel-off type make up}

The present invention relates to a peel-off type makeup foundation composition that can be easily removed upon removal after use on the skin and does not color the skin.

The skin surrounding the whole body is an important part that protects the human body from environmental factors such as various external stimuli and pollution, and is largely divided into epidermis, dermis, and subcutaneous tissue.

The outermost layer of the epidermis is the stratum corneum, which is a part that directly contacts the cosmetic and is a part that can show the condition of cosmetic skin. Through the keratinization process of the epidermal cells, the outermost layer of keratinocytes repeats the detachment and production process, and millions of dead keratinocytes are released from the skin per day and replaced with new keratinocytes. If the keratinization process is not smooth and abnormal keratinocytes are formed or the keratinocytes are not detached smoothly, the skin looks dull and the makeup is poorly received or lifeless.

The commonly used foundation cosmetic composition is commonly used to enable expression of beautiful colors on the face and to hide skin defects.

That is, when applying the foundation to the skin, it should be soft, lightly spread, excellent in skin adhesion and cover of cosmetic effects, and there should be no shine after time, and excellent stability to the skin should be maintained. The types of foundations that are used today include emulsification, powder, and dispersion types, but these foundations contain a lot of silicone oil, hydrocarbon-based oil, ester-based oil, and emulsifier, and when applied to the skin, they are shiny or heavy. There is a problem that not only gives a feeling of use, but also feels frustrating, especially during summer makeup. In addition, a peel-off type pack and an eyebrow coloring product are also used, but when used as a coloring product using a water-soluble pigment, it may be colored on the skin and may come out on the outside. In addition, pigmentation may occur on the skin even after peel-off.

The object of the present invention for solving the above problems is to provide a soothing effect to the skin, including an inorganic pigment and a component having a skin soothing effect, while not being colored on the skin at the same time, and peel-off that does not cause pigmentation even after peel-off. It is to provide a type makeup foundation composition.

Aspects of the present invention for achieving the above object,

3-20% by weight of inorganic pigments; 5 to 20% by weight of a film forming agent consisting of polyvinylpyrrolidone and polyvinyl alcohol; 2-15% by weight of polyols containing methyl propane diol; 0.5 to 10% by weight of silicone oil; And in the peel-off type makeup foundation composition comprising a residual amount of water,

The weight ratio of the inorganic pigment and the film forming agent is 1:0.5 to 1:2,

The methyl propane diol is to provide a peel-off type makeup foundation composition contained in 2 to 9% by weight.

The peel-off type makeup foundation composition of the present invention is not colored on the skin, but is formed of a film film, and unlike the existing makeup products, there is no phenomenon that comes out on the outside, and it is in close contact with the skin and can continuously supply skin soothing ingredients to the skin. .

In addition, the feeling of use is superior to that of the pack type, the skin is not colored, and it can be easily removed from the skin after use, thereby increasing the convenience of use.

1 is a state in which the peel-off type makeup foundation composition according to an embodiment of the present invention is applied to the back of the hand (a), the peel-off state after drying (b), and the state where coloring does not occur after peel-off ( c).
2 is a photograph showing a state in which the peel-off makeup foundation composition is applied to a part of the face (a) and a state in which the peel-off after drying (b) is performed according to an embodiment of the present invention.
3 is a photograph showing a state in which a part of the peel-off is applied after the peel-off makeup foundation composition is applied to the entire face according to an embodiment of the present invention.

The present invention is an inorganic color 3 to 20% by weight; 5 to 20% by weight of a film former formed of polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA); 2-15% by weight of polyols containing methyl propane diol; 0.5 to 10% by weight of silicone oil; And in the peel-off type makeup foundation composition containing the remaining amount of water, the weight ratio of the inorganic pigment and the film-forming agent is 1:0.5 to 1:2, and the methylpropanediol is contained in 2 to 9% by weight -Off-type makeup foundation composition.

Makeup foundation compositions are commonly used to hide beautiful color expression and skin flaws on the skin.

In the present invention, the peel-off type makeup foundation composition of the composition as described above is formed of a film film, so that there is no phenomenon of being exposed to the outside, which is a problem of the existing makeup products, and it is in close contact with the skin so that the skin-generating ingredient can be continuously supplied to the skin. In addition, since pigmentation does not occur even after peel-off because it is not colored on the skin, healthy skin can be maintained.

In one embodiment of the present invention, the peel-off type makeup foundation composition may include an inorganic color.

Since the peel-off type formulation is a water dispersion formulation, the pigments must be well dispersed in water. However, since the coated pigment is hydrophobic, dispersion in the aqueous phase is poor. Therefore, in the present invention, it is preferable to use an uncoated inorganic color.

The inorganic pigment may be preferably one or more selected from the group consisting of titanium dioxide (TiO ₂ ), mica, iron oxide, and silicon.

In the present invention, unlike the colorant using a water-soluble pigment, the inorganic pigment can be developed without coloring on the skin, so that pigmentation does not occur even after peel-off. In addition, the inorganic pigment may be white or colored, and may be a pigment containing a pearling agent.

In one embodiment, the inorganic pigment is more preferably used in a state not coated with, for example, silicones. In the case of using a coated inorganic pigment, dispersion may not be performed well and may not be applied well to the entire skin.

In one embodiment, the content of the inorganic pigment may be included in 3 to 20% by weight, preferably 6 to 18% by weight, more preferably 8 to 14% by weight relative to the total weight of the composition.

If the content of the inorganic pigment is less than 3% by weight, adhesion and color persistence decrease when used on the skin, and when it exceeds 20% by weight, the peel-off effect falls, and after drying, the surface is broken and cannot give a cosmetic effect, and is sticky when used. It can cause stuffiness, etc.

In one embodiment of the present invention, the peel-off type makeup foundation composition may include a film forming agent consisting of polyvinylpyrrolidone and polyvinyl alcohol.

The film forming agent may serve to enable peel-off when used on the skin.

The polyvinylpyrrolidone is a water-soluble polymer used to form the strength of the film, and can improve the texture of irritation, humidity control, flexibility and smoothness of the film, and the polyvinyl alcohol forms a thin film to form the skin. Can be wrapped smoothly and smoothly.

In the present invention, it is preferable that the film-forming agent includes both polyvinylpyrrolidone and polyvinyl alcohol.

When only the polyvinylpyrrolidone is included, a film that is capable of peel-off is not formed, and when only polyvinyl alcohol is included, a strong stimulus is exerted on the skin during peel-off, and the film may harden and break.

In one embodiment, the content of the film forming agent may be included in 5 to 20% by weight, preferably 8 to 15% by weight, more preferably 10 to 14% by weight relative to the total weight of the composition.

If the content of the film forming agent is less than 5% by weight, there may be skin pulling, and it is difficult to use as a product due to poor film formation, and when it exceeds 20% by weight, the viscosity increases and the feeling of use decreases, and the adhesion to the skin is too great May increase skin irritation.

In addition, the polyvinylpyrrolidone may be included in 1 to 10% by weight, preferably 1 to 6% by weight, more preferably 2 to 5% by weight. When the polyvinylpyrrolidone is included outside the above content, the film may be formed too softly or firmly, and user convenience may be deteriorated.

The polyvinyl alcohol may be included in 3 to 18% by weight, preferably 4 to 13% by weight, more preferably 5 to 10% by weight. If the polyvinyl alcohol is included outside the range of the content, the feeling of use may be deteriorated due to skin irritation.

In one embodiment of the present invention, the weight ratio of the inorganic pigment and the film forming agent is 1:0.5 to 1:2, preferably 1:0.7 to 1:1.5, and more preferably 1:1 to 1:1.3.

When the inorganic pigment and the film-forming agent are outside the range of the weight ratio, they are not peeled off and are broken and cannot be released from the skin to give a makeup effect.

In one embodiment of the present invention, the peel-off type makeup foundation composition may include polyols containing methylpropanediol.

The polyols may be included for a skin moisturizing effect, and may further include at least one selected from the group consisting of glycerin, diglycerin, sorbitol, erythritol, and pentaerythritol.

In one embodiment, the polyols containing methyl propane diol may be included in 2 to 15% by weight, preferably 5 to 12% by weight, more preferably 7 to 10% by weight based on the total weight of the composition.

If the content of the polyols is less than 2% by weight, the feeling of use may be deteriorated, and if it exceeds 15% by weight, it does not peel off and breaks off from the skin and cannot give a makeup effect.

In one embodiment, the methyl propane diol may be included in 2 to 9% by weight, preferably 3 to 8.5% by weight, more preferably 4 to 8% by weight, even more preferably 3 to 6% by weight.

If the content of methyl propane diol is less than 2% by weight, the feeling of use may be deteriorated, and if it exceeds 9% by weight, it may be difficult to apply to the skin and the peel-off performance may be deteriorated.

In one embodiment of the present invention, the peel-off type makeup foundation composition may include silicone oil.

The silicone oil may be used as a skin softening agent or conditioning agent for the purpose of alleviating skin irritation by facilitating the removal of the dry film with a moist feeling after peel-off.

The silicone oil may be at least one selected from the group consisting of dimethicone copolyol (DMC), dimethicone, methylpolysiloxane, methylphenylpolysiloxane, methylcyclopolysiloxane, dimethylpolysiloxane, hexamethyldisiloxane and caprylylmethylpolysiloxane. It is not limited to this.

In one embodiment, the content of the silicone oil is 0.5 to 10% by weight, preferably 1 to 7% by weight relative to the total weight of the composition.

When the content of the silicone oil is less than 0.5% by weight, it is impossible to feel a moist feeling upon peel-off, and the dry film is hard, which may irritate the skin when peeling off. When it exceeds 10% by weight, the drying rate is too slow and the stability of the body shape The fall can cause problems.

In one embodiment of the present invention, the weight ratio of the polyvinylpyrrolidone and polyvinyl alcohol is 1:1 to 1:6, preferably 1:2 to 1:5, more preferably 1:2.5 to 1:4.5. to be.

When the polyvinylpyrrolidone and polyvinyl alcohol are included in the peel-off type makeup foundation composition in the weight ratio, excellent spreadability and peel-off effect can be obtained when used on the skin. In addition, when the mixing ratio of the polyvinylpyrrolidone and the polyvinyl alcohol exceeds the weight ratio, the color persistence may be reduced, and when used on the skin, such as face pulling, the feeling of use may be reduced, and when peeling off, the skin may be irritated.

In one embodiment of the present invention, the peel-off type makeup foundation composition may further include lower alcohol.

The lower alcohol is at least one selected from the group consisting of ethanol, methanol, propanol and butanol.

The alcohol can be absorbed into the skin and volatilized, thereby contributing to shortening the drying time of the peel-off type makeup foundation composition.

In the present invention, the peel-off type makeup foundation composition may further include one or more additives selected from the group consisting of skin nutritional agents, skin elasticity improving agents, antioxidants, anti-irritants, skin soothing agents and fragrances, but is not limited thereto. It is not.

The skin soothing agent is a raw material having a skin soothing effect and may exhibit excellent effects such as skin soothing, skin barrier strengthening, anti-inflammatory, and irritation relief. The skin soothing agent may preferably include allantoin or dipotassium glycyrrhizate.

The additive may be included in 1 to 20% by weight, preferably 5 to 15% by weight based on the total weight of the composition.

In addition, the peel-off type makeup foundation composition may further include purified water in order to improve compounding workability with other compounds. The purified water may be deionized water or distilled water.

Hereinafter, the present invention will be described in more detail through the following examples, but the scope of the present invention is not limited to the examples.

<Manufacturing method>

After adding purified water to a vacuum emulsifying stirring tank capable of temperature control, stirring, and homo-processing, warm it to 70 to 90°C, and then add additives. This is maintained by stirring at a rotational speed of 2,500 to 3,500 rpm using a paddle mixer and a homo mixer at 10 to 40 rpm, and a film forming agent is added. After maintaining the temperature and the stirring speed, the polyols are slowly added and neutralized. When neutralization is complete, cool to 35℃ and homogenize by adding ethanol.

After adding the silicone oil to the inorganic pigment and additives at 35 ℃ to prepare a peel-off type makeup foundation composition.

Test Example 1

Initial spreadability evaluation

To compare the spreadability of Examples 1 to 7 described in Table 1, and Comparative Examples 1 to 12 described in Table 2 and Table 3, the spreadability of each composition was measured according to the following method and the results are shown in Table 4 and Table below. It is shown in 5.

A certain amount (1 g) of the contents was taken on a glass plate, and then applied to the same thickness of 0.1 mm using an applicator, followed by complete drying. The state of the contents pushed out to the glass plate, that is, the length was measured and observed with a ruler. When the contents of the same content are applied to the same thickness, the length up to the point where the slip is applied is measured. Therefore, the longer the measured length, the more the content is measured, and the contents can be evaluated as being excellent in spreading. The results are shown in Tables 4 and 5.

Item Example One 2 3 4 5 6 7 ³⁾ Length 6.7 8.6 7.8 7.6 6.4 6.2 6.0

³⁾ Length: The length that is pushed out and the unit is cm.

As shown in Tables 4 and 5, it can be seen that Examples 1 to 7 had better initial spreadability than Comparative Examples 1 to 12.

Test Example 2

Sensory evaluation of peel-off type makeup foundation composition

After using the prepared peel-off type makeup foundation composition for 100 women in their 20s and 30s for 7-10 days, the results of use were compared and evaluated.

The sensory evaluation was performed on the items of adhesion, color persistence, feeling of use, degree of staining and ease of removal, and the evaluation criteria were 1 (very dissatisfied) to 10 (very satisfied), and the results are shown in Table 6 below.

Adhesion Color lasting Usability Degree Ease of removal Example 1 9 10 8 9 8 Example 2 9 10 8 10 8 Example 3 9 10 9 10 9 Example 4 9 9 9 9 9 Example 5 8 8 8 7 8 Example 6 8 8 8 8 7 Example 7 7 7 7 7 6 Comparative Example 1 6 9 6 8 6 Comparative Example 2 7 6 6 6 5 Comparative Example 3 6 7 5 6 5 Comparative Example 4 6 8 4 6 5 Comparative Example 5 6 8 3 5 5 Comparative Example 6 6 6 6 5 5 Comparative Example 7 6 6 3 6 4 Comparative Example 8 5 6 5 5 4 Comparative Example 9 5 7 6 9 8 Comparative Example 10 6 7 6 8 6 Comparative Example 11 5 6 6 6 5 Comparative Example 12 4 5 6 6 3

As shown in Table 6 above, it can be seen that Examples 1 to 7 all showed higher satisfaction than Comparative Examples 1 to 12 for five items of adhesive color persistence, feeling of use, degree of staining, and ease of removal. However, in Example 7 using titanium dioxide coated with silicon as an inorganic pigment, dispersion was not well performed, and thus, in terms of feeling of use, satisfaction was somewhat lower than that of other Examples. In addition, Examples 5 and 6 outside the preferred weight ratio of polyvinylpyrrolidone and polyvinyl alcohol were also slightly lower in satisfaction than other examples.

In particular, in Comparative Example 1, which was outside the content of the inorganic pigment, a feeling of use was poor, adhesion and a film film breakage occurred.

In addition, Comparative Examples 2 and 3, which alone included polyvinylpyrrolidone or polyvinyl alcohol as a film-forming agent, did not completely form a film or did not easily adhere to the skin and had difficulty in removal.

In the case of Comparative Example 4 using a small amount of methylpropanediol, the removal and the feeling of use were very poor, and the drying speed of Comparative Example 5 exceeding the mefilpropanediol content was slow, causing a slight staining phenomenon.

Comparative Examples 6 to 8 using only propylene glycol, dipropylene glycol or butylene glycol without any methyl propane diol have a slower drying rate and less skin adhesion with slippery formulations than when using methyl propane diol. This occurred.

In addition, Comparative Examples 9 and 10, which are outside the weight ratio of the inorganic pigment and the film forming agent, are not easily removed when applied to the skin.

Comparative Examples 11 and 12 outside the content of the preferred range of the film forming agent were too sticky, were not easy to apply to the skin, and were not easy to remove (the peel off was not good).

Therefore, when the peel-off type makeup foundation composition of the present invention is used, the skin adhesion is excellent, and the color persistence is excellent without forming a film film and being exposed to the outside.

In addition, the feeling of use is superior to that of the pack type, the skin is not colored, and it can be easily removed from the skin.
